Quota delegation for complex environments

In complex environments customers of IaaS cloud providers are not individual users but rather organizations with a complex sub-structure on their own.
In this case the person who requests a project is not necessarily the (main) user of these resources. He'd rather like to be able to share them between different
groups inside his own organization, and allow them to use a certain fraction of the resources in the organization's project.
Quota delegation will allow an organization's stake holder to buy resources on behalf of his organization, chop them down into different shares and re-allocated these
internally to other people inside the organization.
In this scenario the cloud administrator allocates only one project to the organization (represented by an individual or a group of individuals),
along with a certain amount of quota. Accounting will be done for this project for the full organization, and the cloud administrator has no need to know about sub-structures
of his customer. This is expected to dramatically reduce the operational cost of running the cloud infrastructure.
In turn, large customers gain full control over their resources without having to interact with the cloud administrator for internal changes inside the organization.
